    Well, I never tested the BLDC output from the MMos board myself. But the creator of the MMos firmware stated in his thread at virtualracing.org that he implemented BLDC support but never tested it himself. I also found no reference of someone else giving it a try.

    That is interesting! How is your progress? Does the motor react to the FFB input correctly?

    Ok, got it.
    I never tried two IBT2 for that. So I cannot provide any trustable/proofed schematics, sorry.

    Progress is slow due few time available because of work and family.
    Positive on HW side: the IFX shield is easy to work with, had no problem with the toolchain.
    Still lot of issues on my code. The motor reacts to FFB but can not say it does...correctly. Lot of spikes. Guess I have to rework the lookup tables but had no time. Let's hope in holidays...

    The wheel project will remain on the IFX, expecially now that I hope to mix the BLDC control code with the AIW you provided (thank you!).

    I was looking at the IBT as a cheaper solution for another later project involving multiple motors. I was looking at the ODrive for that. I like that project very much but was too much for a single motor. But with 2 the 2x IFX cost is not much low.
    The 2xIBT would be a very cheap solution.

    Do you use shielded and grounded wires for the control and encoder signals? Maybe some interference causes the spikes.

    I think the AIW source came from fernando igor, not me.

    Yep all shielded and grounded. I really think problem is my sw. Wll sort it out.

    I know the code is from Fernando. But you posted the git link. I was not able to found it myself

    The IFX007T it's a good solution and easy to install because put the board on Arduino and the current output is very high.

    Yes it is a very nice board. Another interesting one from same source is the TLE9879, you can stack up to 4 on a single Arduino. Would be a very nice solution for multiple motor control. Sadly it is not fine for hoverboard motors because of the max 10A rating. Indeed this spec is reported in the product homepage but I did not find any in the tech docs. Still think Odrive is te better solution for multiple BLDC motors. Like maybe in a motion platform...

    I didn't notice these boards yet. Good find!

    The SPIN3204 will not be suitable, I guess. Although the databrief states FOC drivability, I did not see anything in the manuals.

    But the SPIN3201 seems to be a worthwhile candidate. The 3201 is designed for FOC drive and has three shunt current sensing. The other specs are almost identical. Even over-current protection is in a range suitable for our needs (20A/65A/140A).

    This board could be a good alternative to the F303RE/IHM08M1 combo.
